In this article, a novel calculation procedure using optimization techniques is proposed to compute the torsion–shear interaction curves for reinforced concrete (RC) beams. The applied NBR 6118 and AASHTO LRFD standards in order evaluate their reliability. For this, some experimental results found literature related RC beams tested under combined torsion shear, as well from combined-action soft...

Prinsip dasar dari pekerjaan tanah untuk jalan adalah dapat menyediakan ruang yang dibutuhkan pergerakan lalu lintas dengan aman dan lancar, sebagai pondasi tumpuan badan harus mampu mendukung beban disalurkan melalui perkerasan tanpa terjadi deformasi berarti. Tujuan Penelitian mengetahui sifat fisik Kecamatan Moncongloe, Untuk pengaruh penambahan semen abu sekam padi terhadap kepadatan lempun...

This paper presents a computational framework for optimal design of non-prismatic reinforced concrete box girder bridges. The variables include the geometry of the cross section, tapered length, concrete strength and reinforcement of box girders and slabs. These are obtained by the enhanced colliding bodies optimization algorithm to optimizing the cost and again CO2 emission. Loading and design...

Particularly, concrete material involvements creep under a continuous load and practices shrinkage due to variations in humidity proportion. These physical properties growth over time. Prestressed losses according will lead loss of compression strength for concrete. Time-dependent analysis is important essential two types prestressed which are pretensioned posttensioned with the effect time, st...
